Silent and noiseless JOSEF intermediate relay DZY-210 working voltage 220VDC board wiring

Description :

　　The DZY-210 intermediate relay is a DC voltage type intermediate relay mainly used in power systems and automation control systems to increase the number and capacity of contacts and meet complex control requirements.

　　The relay adopts a valve type electromagnetic structure design, and its core components include coils, magnetic conductors, armatures, and contact systems. The coil is usually mounted on a "П" - shaped or "U" - shaped magnetic conductor, with a movable armature above the magnetic conductor and two rows of contact systems on both sides of the magnetic conductor. When the excitation applied to the coil is equal to or greater than its operating value, the armature is attracted to the guide magnet, and at the same time, the armature presses the contact spring, causing the contact to connect, disconnect, or switch the controlled circuit. When the coil of the relay is powered off or the excitation amount decreases to less than its return value, the armature and contact piece return to their original positions.

　　The DZY-210 intermediate relay has multiple rated voltage options, such as 12V, 24V, 36V, 48V, 60V, 100V, 110V, 127V, 220V, and 380V, to adapt to different application environments. In addition, its contact capacity is large and can withstand high currents and voltages, ensuring the stable operation of the circuit. The contact forms are diverse, the combination is flexible, the application range is wide, and the adaptability is strong.

　　The relay also adopts a flame-retardant shell design, with strict monitoring of material quality, which is superior to ordinary materials, making it safer and has a longer service life. At the same time, its alloy terminal design makes wiring more convenient, can be tightened with just one plug, and has good conductivity.

　　In terms of application fields, DZY-210 intermediate relays are widely used in various scenarios such as new energy, metallurgical steel rolling, urban construction and transportation, nuclear power plants, petrochemicals, and mining factories. Its stable performance and reliable working characteristics enable it to meet control requirements in various complex and harsh environments.
